DETAILED DESCRIPTION OF THE EMBODIMENT

Characteristics of a first embodiment of the present invention will be described below with reference to FIG. 1 and FIG. 2. As shown in FIG. 1, eleven slot game areas A1 to A11 are provided on a lower display 16 (corresponding to the “display” in claims). A slot game is executed in each of the slot game areas A1 to A11.

The slot game areas A1 to A11 include one large slot game area A1 (corresponding to a “specific slot game area” in claims) in the center and ten small slot game areas A2 to A11 arranged therearound.

Display areas of three rows by three columns are provided in the respective slot game areas A2 to A11 except the central slot game area A1. A credit(s) (corresponding to the “gaming media”) is bet by an insertion of a medal(s) or pressing of a bet switch 25. Symbols displayed (arranged) in the display areas are scrolled when a start switch 27 has been pressed and then the symbols stop (rearranged) in each of the display areas. In this manner, the slot game is executed in each of the slot game areas A2 to A11.

In the slot game executed in each of the slot game areas A2 to A11 except the central slot game area A1, up to three credits can be bet and the number of activated paylines increases as a bet amount increases in each slot game.

On the other hand, display areas of one row by three columns are provided on the central slot game area A1. On the slot game area A1, the symbols displayed (arranged) in each of the display areas are scrolled when a prescribed condition has been met in the slot games executed on the slot game areas A2 to A11 and then the symbols stop (rearranged) in each of the display areas. In this manner, the slot game is executed on the slot game area A1.

In addition, since the display areas on the central slot game area A1 is configured with one row by three columns, the central slot game area A1 has only one payline. As a result, only one credit can be bet on the slot game executed on the central slot game area A1.

The surrounding ten slot game areas A2 to A11 are displayed on an LCD panel 17 provided in the lower display 16. The configuration of the LCD panel 17 will be described later with reference to FIG. 3 and FIG. 4.

The central slot game area A1 is displayed by three mechanical spinning reels 3A to 3C arranged behind in a center area of the LCD panel 17. Each of the reels 3A to 3C is spun by each of stepping motors 45A to 45C (see FIG. 5). A plurality of symbols is disposed on a peripheral surface of each of the reels 3A to 3C with at some intervals. It is possible for the player to visually recognize part of the peripheral surface of each of the reels 3A to 3C through a constantly transmissive area (slot game area A1) in the center of the LCD panel 17.

The lower display 16 on which the slot game areas A1 to A11 are displayed is arranged in a center of a front face of a slot machine 10. In the slot machine 10, a bet can be placed on each of the slot game areas A1 to A11 when a medal(s) is inserted into a medal insertion slot 21 provided below the lower display 16 (or a bet may be placed with internally stored credits by the pressing of the bet switch 25). The player can select (activate) the slot game areas A1 to A11 to be bet (activated) arbitrarily. In other words, the player can select (activate the slot game areas A1 to A11 on which games are executed with a bet placed. For example, it is possible for the player to activate each of the slot game areas A1 to A11 by touching it. The operation of touching the slot game areas A1 to A11 can be detected by a touch screen 72 provided on a surface of the LCD panel 17.

For example, one bet is placed on the slot game area A1 when the player inserts one medal into the medal insertion slot 21 after touching the slot game area A1. And then, one more bet is placed on the slot game area A1 when the second medal is inserted further. However, a bet is placed preferentially on the slot game areas A2 to A11 on which a bonus game (this bonus game is a normal bonus game which is different from a jackpot bonus game) is being executed. This will be further described in detail later with reference to FIG. 20. In addition, as described above, only one bet can be placed on the central slot game area A1.

It may also be possible that the player previously selects (activates) a slot game area(s) by touching the game area(s) and then places a bet(s) on the activated slot game area(s) randomly by inserting a medal(s).

Some of a bet amount is accumulated for a jackpot. The jackpot is shared with other slot machines. Consequently, a jackpot payout is provided to a player of a jackpot-winning slot machine when a jackpot winning is awarded in any of the slot machines that share the jackpot.

After a bet is placed on the slot game, a payout (payout of a medal(s), or addition of credits) is provided according to the bet amount and a winning combination when the winning combination is achieved on the payline in the slot game on each of activated slot game areas A2 to A11 except the central slot game area A1.

In addition, the jackpot bonus game is executed on the central slot game area A1 only when the slot game on any of the activated slot game areas A2 to A11 except the central slot game area A1 have met a prescribed condition. The prescribed condition is, for example, a case where the symbol combination of the jackpot bonus trigger is achieved on any of the slot games on the slot game areas A2 to A11. Alternatively, it may also be possible to regard that the prescribed condition is met when a mere winning combination is achieved on any of the slot game areas A2 to A11 instead of the symbol combination of the jackpot bonus trigger. It is obviously possible to regard that the prescribed condition is met when a trigger combination or a winning combination is achieved in the predetermined number or more (for example, two or more) of slot games on the slot game areas A2 to A11. On the contrary, it may also be possible to regard that the prescribed condition is met when a winning combination is not achieved on any of the slot game areas A2 to A11.

Further, it may also be possible to regard that the prescribed condition is met only when the trigger combination is achieved on any of the activated slot game areas A2 to A11. Alternatively, it may be possible to regard that the prescribed condition is met when the trigger combination is achieved on any of the slot game areas A2 to A11 regardless of activation.

Then, a jackpot payout is provided to the player in case where a bet was placed on the central slot game area A1 and then the jackpot bonus game on the central slot game area A1 has brought the jackpot winning combination. The jackpot payout may be a payout of actual medals or may be added to the internally stored credits. In addition, the jackpot payout amount may be the entire accumulated amount or may be varied (constant amount or variable amount) according to the achieved jackpot winning combination.

In the present embodiment, a bet is placed on the slot game areas A1 to A11 by the insertion of a medal(s), however, a bet may be placed using a coin, bill, bar coded ticket, etc. In addition, in the present embodiment, the symbols are scrolled and then stopped again in the slot game on each of the slot game areas A2 to A11 except the central slot game area A1. However, the slot game on each of the slot game areas A2 to A11 is not limited to that in which the symbols are scrolled. For example, the symbols may be successively switched over in each of the display areas and then stopped.

Further, in the present embodiment, a maximum bet amount is set to three on the slot game areas A2 to A11 except the central slot game area A1. However, the maximum bet amount is not limited to this. If two or more rows of the display areas are provided on the central slot game area A1, the number of activated paylines can be increased according to a bet amount.

The controller 40 of the slot machine 10 is a microcomputer and includes interface circuits 102, an input/output (I/O) bus 104, a CPU 106, a ROM 108, a RAM 110, a signal communication interface (I/F) circuit 111, a random number generator (RNG) 112, a motor drive circuit 120, a speaker drive circuit 122, a hopper drive circuit 124, a display control circuit 128, and a display controller 140.

The interface circuits 102 are connected to the I/O bus 104. The I/O bus 104 inputs/outputs data signals and address signals to/from the CPU 106.

The start switch 27 is connected to the interface circuits 102. A start signal output from the start switch 27 is transmitted to the CPU 106 via the I/O bus 104, after having been converted into a predetermined signal by the interface circuits 102.

The bet switch 25, the max-bet switch 24, the spin/repeat-bet switch 26, and the cash-out switch 23 are connected to the interface circuits 102. A switching signal output from each of the switches 23 to 26 is transmitted to the CPU 106 via the I/O bus 104, after having been converted into a predetermined signal by the interface circuits 102.

A medal sensor 43 is connected to the interface circuits 102. The medal sensor 43 detects a medal(s), which has been inserted into the medal insertion slot 21. The medal sensor 43 is provided inside the medal insertion slot 21. The detection signal output from the medal sensor 43 is transmitted to the CPU 106 via the I/O bus 104, after having been converted into a predetermined signal by the interface circuits 102.

The touch screen 72 described above is connected to the interface circuits 102. The touch screen 72 detects the touch operation onto the slot game areas A1 to A11 displayed on the lower display 16 by a player. The touch screen 72 is provided on the surface of the LCD panel 17. A position signal output from the touch screen 72 is transmitted to the CPU 106 via the I/O bus 104, after having been converted into a predetermined signal by the interface circuits 102.

The ROM 108 storing system programs and the RAM 110 storing various data are connected to the I/O bus 104. The RNG 112, the signal communication I/F circuit 111, the motor drive circuit 120, the display controller 140, the hopper drive circuit 124, the speaker drive circuit 122, and the display control circuit 128 are connected to the I/O bus 104.

The CPU 106, triggered by receiving the start signal from the start switch 27, reads a game execution program among the system programs stored in the ROM 108 and executes a game. The game execution program is a program for executing the slot game in each of the slot game areas A1 to A11 on the lower display 16 using the motor drive circuit 120 and the display controller 140.

In other words, the game execution program is programmed so as to execute a slot game in which symbols are rearranged after scrolling in each of the slot game areas A1 to A11 and a payout is provided when a winning combination is achieved on an activated payline.

The signal communication I/F circuit 111, which is connected to a hall server etc., transmits gaming history data etc. of the slot machine 10 to the hall server. The signal communication I/F circuit 111 receives various data transmitted from the hall server.

The RNG 112 generates a random number for determining whether or not to achieve a winning combination in the slot game on each of the slot game areas A1 to A11.

The display control circuit 128 controls displaying a payout amount on the payout counter 48 provided at the lower left area of the lower display 16 (LCD panel 17).

The speaker drive circuit 122 outputs sound data to the speakers 29. In other words, the CPU 106 reads the sound data stored in the ROM 108 and transmits the sound data to the speaker drive circuit 122 via the I/O bus 104. In this manner, predetermined sound effects are generated via the speakers 29.

The hopper drive circuit 124 outputs a cash-out signal to the hopper 44 when providing a cash-out. In other words, the CPU 106 outputs a drive signal to the hopper drive circuit 124 via the I/O bus 104 when receiving the cash-out signal from the cash-out switch 23. As a result, the hopper 44 cashes out medals equivalent to the credits stored at that time in a predetermined memory area of the RAM 110.

The motor drive circuit 120 is configured by including a reel CPU, a reel ROM, and a reel RAM internally. In detail, the CPU 106 generates a command signal relating to a symbol display according to status and an outcome of the slot game on the slot game area A1 and outputs the command signal to the motor drive circuit 120 via the I/O bus 104. Upon receipt of the command signal, the motor drive circuit 120 generates drive signals for the stepping motors 45A to 45C, which spins or stops each of the reels 3A to 3C based on the command signal. And then, the motor drive circuit 120 outputs the drive signals to the stepping motors 45A to 45C, respectively. In this manner, the slot game is executed (predetermined images are displayed) on the slot game area A1.

The display controller 140 controls the execution of the slot game on each of the slot game areas A2 to A11 around the slot game area A1. In detail, the CPU 106 generates an image display signal according to status and an outcome of the slot game on each of the slot game areas A2 to A11 and outputs the image display signal to the display controller 140 via the I/O bus 104. Upon receipt of the image display signal, the display controller 140 generates a drive signal of the LCD panel 17 based on the image display signal. And then, the display controller 140 outputs the drive signal to the LCD panel 17. In this manner, the slot game is executed (predetermined images are displayed) on each of the slot game areas A2 to A11.

FIG. 3 is a perspective view when the LCD panel 17 is viewed from behind. FIG. 4 is an exploded perspective view when viewed from the front. Some parts shown in FIG. 3 are omitted (not shown) in FIG. 4.

The LCD panel 17 has a shape and size corresponding to the lower display 16. As shown in FIG. 3 and FIG. 4, the LCD panel 17 is constituted by overlapping a liquid crystal unit 74, a light guide plate 75, and a reflective film 76 in the order from the front side of the slot machine 10.

The liquid crystal unit 74 is constituted by filling liquid crystal between a transparent substrate, such as a glass plate on which a thin film transistor layer is formed, and another transparent substrate in opposition thereto. The liquid crystal unit 74 changes colorless in an inactive state, in which no image is displayed. In the inactive state, the transmitted light can be visually recognized from the outside. The central area of the liquid crystal unit 74 is always inactive (transmissive) in order for a player to visually recognize the reels 3A to 3C.

The light guide plate 75 guides light from fluorescent tubes 77 a, 77 b to the inside of the liquid crystal unit 74 to illuminate the liquid crystal unit 74 from the backside. Specifically, the light guide plate 75 is a transparent member having a thickness of about 2 cm and made of acryl resin etc. The light guide plate 75 is made of a material having light guiding feature. The fluorescent tubes 77 a, 77 b are attached on upper and lower ends of the light guide plate 75 by lamp holders 79 a to 79 d.

The reflective film 76 has a transparent film as a substrate, such as a polyester film etc. The reflective film 76 has a non-reflective area 76B and a reflective area 76A therearound. The shape, position, and size of the non-reflective area 76B are the same as those of the central slot game area A1. The non-reflective area 76B is a light transmissive plane made of the substrate. The reflective area 76A is made by depositing a thin aluminum or silver layer on the substrate.

The reflective area 76A of the reflective film 76 partially reflects light introduced into the inside of the light guide plate 75 from the upper and lower ends thereof. And then, the reflective area 76A outputs the light frontward. The reflective area 76A prevents light from leaking backward and effectively outputs the light frontward.

Fluorescent tubes 78 a, 78 b are disposed behind the reflective film 76 with lamp holders 79 e to 79 h. The fluorescent tubes 78 a, 78 b illuminate the periphery of the reels 3A to 3C from above and beneath.

An outer plate 73 is disposed in front of the liquid crystal unit 74. The touch screen 72 is arranged on the surface of the outer plate 73. The touch screen 72 detects player's touch operations etc. The touch screen 72 is made of a transmissive member. The outer plate 73 is made of a transmissive member and images, such as patterns, characters, etc., are drawn on its surface. The images are drawn on the areas outside the slot game areas A1 to A11. The player can see the images drawn on the areas outside the areas A1 to A11 when playing with the slot machine 10. The outer plate 73 may be omissible.

Next, images displayed on the slot game areas A1 to A11 are explained with reference to FIG. 13 and FIG. 14. FIG. 13 is a display example of the central slot game area A1 and FIG. 14 is a display example of the slot game areas A2 to A11.

As shown in FIG. 13, three (one row by three column) display areas q1 to q3 are provided on the central slot game area A1. Symbols are scrolled by the reels 3A to 3C in each of the display areas q1 to q3 when the jackpot bonus game is started.

Then, a jackpot payout is awarded when a jackpot winning combination is achieved in the display areas q1 to q3 of the central slot game area A1.

As shown in FIG. 14, nine (three row by three column) display areas q11 to q33 are provided on each of the slot game areas A2 to A11. Symbols are scrolled in each of the columns of the display areas q11 to q33 on the LCD panel 17 when the slot game is started on each of the slot game areas A2 to A11.

Five LEDs 53 a to 53 e are provided on the left side of the display areas q11 to q33 of each of the slot game areas A2 to A11. The LEDs 53 a to 53 e notify the activated payline(s) on each of the slot game areas A2 to A11. As shown in FIG. 15, five paylines are prepared on the display areas q11 to q33. A horizontal line in the middle row is L1, a horizontal line in the upper row is L2, a horizontal line in the lower row is L3, a diagonal line going down to the right is L4, and a diagonal line going up to the right is L5.

The LEDs 53 a to 53 e light up according to a bet amount. In detail, only the LED 53 a lights up when one credit is bet. The LEDs 53 b, 53 c, in addition to the LED 53 a, light up when two credits are bet. The LEDs 53 d, 53 e, in addition to the LEDs 53 a to 53 c, light up when three credits are bet.

It is indicated that the line L1 has been activated, when the LED 53 a lights up. In addition, it is indicated that the lines L2, L3 have been activated, respectively, when the LEDs 53 b, 53 c light up. Furthermore, it is indicated that the lines L4, L5 have been activated, respectively, when the LEDs 53 d, 53 e light up. As a result, only the line L1 is activated when one credit has been bet, the lines L1, L2, and L3 are activated when two credits have been bet, and all of the lines L1 to L5 are activated when three credits have been bet. Then, a payout is awarded according to a winning combination(s) when the winning combination(s) is achieved on the activated payline (s).

An activation indicating frame 51 is provided on each peripheral edge of the slot game areas A1 to A11. Each of the activation indicating frames 51 lights up on the LCD panel 17 for the activated slot game areas A1 to A11. The activation indicating frame 51 lights up on the slot game areas A1 to A11 on which at least one credit is bet. It is possible for a player to easily recognize the activated slot game area(s) by the activation indicating frame(s) 51.

A bonus game indicator 52 is provided above each of the slot game areas A2 to A11 except the central slot game area A1. The bonus game indicator 52 of each of the slot game area A2 to A11 lights up on the LCD panel 17 during a bonus game (a normal bonus game being different from the above-described jackpot bonus game, to be described later). It is possible for a player to easily recognize the slot game area(s) during the bonus game by the bonus game indicator(s) 52.

FIG. 16 shows winning combinations in the slot game on the slot game areas A2 to A11. As shown in FIG. 16, the jackpot bonus game is started on the central slot game area A1 when three JACKPOT-7's are rearranged on the activated payline (e.g., the three JACKPOT-7's are rearranged on the line L1 (FIG. 15) when the line L1 has been activated). The bonus game is started on the own slot game area when three 7's are rearranged on the activated payline, a 15-credits payout is awarded to the player when three APPLEs are rearranged, a 10-credits payout is awarded when three BELLs are rearranged, and a 2-credits payout is awarded when a “CHERRY” is rearranged on the leftmost of the activated payline.

FIG. 17 shows jackpot winning combinations in the jackpot bonus game on the central slot game area A1. As shown in FIG. 17, the entire accumulated jackpot amount is awarded as a jackpot bonus when three 7's are rearranged. A half of the accumulated jackpot amount is awarded as a jackpot bonus when three APPLEs are rearranged. Further, a quarter of the accumulated jackpot amount is awarded as a jackpot bonus when three BELLs are rearranged.

Next, an operation of the slot machine of the present embodiment is described with reference to flowcharts shown in FIG. 6 to FIG. 12. FIG. 6 is a flowchart showing slot game execution processing. The slot game execution processing is executed by the CPU 106 (FIG. 5) according to the game execution programs stored in the ROM 108.

First, the CPU 106 executes area activation receiving processing for receiving a selection for activating slot game areas A1 to A11 (step S11). In the area activation receiving processing, the slot game areas A1 to A11, which have been touched by the player to activate, are detected by the touch screen 72. Then, the CPU 106 activates the touched slot game areas A1 to A11 (step S12). The CPU 106 lights up the activation indicating frame 51 on the peripheral edge of the activated slot game area(s) to notify the player of the activated slot game area(s).

For example, when the slot game areas A1 to A6 has been activated, the activation indicating frames 51 of the activated slot game areas A1 to A6 are lit up and the activation indicating frames 51 of the non-activated slot game areas A7 to A11 are not lit up, as shown in FIG. 18.

Next, the CPU 106 executes bet amount receiving processing for receiving a total bet amount on the slot games on the activated slot game areas A1 to A11 (step S13). In the bet amount receiving processing, pressing of the bet switch 25 by the player is detected and the bet total amount is calculated. Then, the CPU 106 subtracts the bet amount having been input from an internally stored credit amount (step S14). For example, if the stored credit amount is 50 credits and a 30-credits bet amount is received, the stored credit amount will be 20 credits.

It is also possible to place a bet on each slot game on the activated slot game areas A1 to A11 by inserting a medal (s) into the medal insertion slot 21. In this case, the CPU 106 recognizes the number of inserted medals as a bet amount. In this case, it is not needed to execute subtraction from the stored credit amount in step S14.

Next, the CPU 106 executes bet processing for placing a bet on each of the slot games on the activated slot game areas A1 to A11 (step S15). The bet processing will be described later in detail with reference to FIG. 10 and FIG. 11.

After step S15, the CPU 106 determines a payline(s) to be activated according to the bet amount for each of the slot game areas A2 to A11 except the central slot game area A1 (step S16). In this processing, as described above, the line L1 is activated when one credit is bet on each of the slot games on the slot game areas A2 to A11, the lines L1, L2, and L3 are activated when two credits are bet, and all of the lines L1 to L5 are activated when three credits are bet (see FIG. 15).

Although a detailed description will be given later, it is also possible to place a bet randomly on each slot game on the slot game areas A1 to A11. In this case, it is not limited that a bet is placed on each of the slot game areas A1 to A11 in numerical order of the areas. For example, when the slot game areas A1, A3, A6, A8, and A9 are activated, one credit is bet, respectively, in the order of A8, A3, A9, A1, and A6.

Then, the CPU 106 determines whether or not the start switch 27 has been pressed (step S17). The slot game is executed on each of the slot game areas A2 to A11 except the central slot game area A1 when the start switch 27 has been pressed (step S18).

Next, the CPU 106 determines whether or not an outcome of the slot games on the slot game areas A2 to A11 has met a prescribed condition, respectively (step S19). Here, it is determined that the prescribed condition has been met when a jackpot bonus trigger combination (three JACKPOT-7's: FIG. 16) is achieved on an activated paylines in at least one slot game (including the bonus game) on activated slot game areas A2 to A11. The present processing ends when the prescribed condition has not been met (step S19: NO). On the other hand, the CPU 106 executes the jackpot bonus game on the central slot game area A1 (step S19-1) when the prescribed condition has been met (step S19: YES). Then, the present processing ends.

Next, a processing procedure of the slot game executed on each of the activated slot game areas A2 to A11 is described with reference to FIG. 7. In the following description, a slot game in an activated slot game area A6 is described as an example. In the present embodiment, a slot game(s) is executed also in a non-activated slot game area(s). However, no payout is awarded even if a winning combination is achieved and a trigger combination does not cause a trigger in respect to the non-activated slot game area(s).

First, the CPU 106 determines whether a bonus flag of the slot game area A6 is “0” or “1” (step S21). The default value of the bonus flag is “0” and set to “1” when the bonus game is to be executed.

The CPU 106 determines symbols to be stopped (hereinafter, simply referred to as stop symbols) in each of the display areas q11 to q33 on the slot game area A6 when the bonus flag is “0” (step S23). By this processing, symbols (“JACKPOT-7”, “7”, “BELL”, “APPLE”, etc.) to be displayed in each of the display areas q11 to q33 are determined.

Next, the CPU 106 scrolls symbols in the display areas q11 to q33 (step S24). Then, the symbols stop in each of the display areas q11 to q33 after a predetermined time has elapsed. The displayed symbols at this time are the stop symbols determined in step S23.

Then, the CPU 106 determines whether or not a bonus trigger combination (three 7's: FIG. 16) is rearranged on any of the activated paylines (step S25). For example, it is determined whether or not the bonus trigger combination is achieved on any of the paylines L1 to L5 (FIG. 15) when all of the lines L1 to L5 are activated.

Then, the CPU 106 executes bonus game starting processing (step S26) when the bonus trigger combination is achieved on any of the paylines L1 to L5. The bonus game starting processing will be described later with FIG. 8.

On the other hand, the CPU 106 determines whether or not one of winning combinations has been achieved on any of the activated paylines (step S27) when the bonus trigger combination has not been achieved. A payout is awarded according to a winning combination (step S28) when the winning combination has been achieved. On the other hand, the CPU 106 does not award a payout when a winning combination has not been achieved. And then the CPU 16 ends the slot game. It may be possible to cash-out a medal(s) equivalent to a payout amount through the cash-out chute 28 or to add a credit(s) equivalent to a payout amount to the internally stored credits, when a payout is to be awarded.

Next, the bonus game starting processing is described with reference to the flowchart in FIG. 8. The bonus flag is set to “1” (step S31) when the bonus trigger is achieved in step S25 in FIG. 7. At this time, the bonus game indicator 52 of the slot game area A6 lights up as shown in FIG. 19 to notify the player that the bonus game is being executed on the slot game area A6.

Then, the CPU 106 determines the number of the bonus games T (step S32). The number of games T is, for example, fifty. The number of games T may be fixed or determined each time randomly by the CPU 106. The number of games T is stored in the RAM 110.

Next, a payout for the bonus trigger is awarded (step S33). For example, a 15-credits (15-medals) payout is awarded in the present embodiment. Then, the present processing is ended.

Bonus game execution processing is executed (step S22) for the next slot game on the slot game area A6 after step 21 in FIG. 7, when the bonus flag has been set to “1” in the bonus game start processing (step S31 in FIG. 8).

The bonus game execution processing is described below with reference to the flowchart in FIG. 9. The CPU 106 executes processing for determining stop symbols (step S41) when the bonus game execution is started. This processing is the same processing as that in step S23 in FIG. 7. In step S41, three 7's are not rearranged on the payline, but the stop symbols are determined so that a winning combination is achieved with a high probability. In other words, a winning combination (three BELLs, three APPLEs or at least one CHERRY on the leftmost in FIG. 16) is achieved on an activated payline with higher probability in the bonus game than in the normal game.

Next, the CPU 106 scrolls the symbols in the display areas q11 to q33 (step S42). This processing is the same as that in step S24 in FIG. 7. Then, the symbols stop in each of the display areas q11 to q33 after a predetermined time has elapsed. At this time, the displayed symbols are the stop symbols determined in step S41.

Next, the CPU 106 determines whether or not a winning combination has been achieved on the activated payline (step S43). A payout is awarded according to a winning combination (step S44) when the winning combination has been achieved. On the other hand, the CPU 106 does not award a payout when a winning combination has not been achieved.

Then, the CPU 106 decrements the number of games T stored in the RAM 110 (step S45).

Next, the CPU 106 determines whether or not the number of games T is “0” (step S46). The bonus flag is reset to “0” when “T=0” (step S47). In other words, the bonus flag is reset and the bonus game is ended when the predetermined number of bonus games has been expended.

Next, the bet processing (step S15 in FIG. 6) is described with reference to a flowchart in FIG. 10 and a table in FIG. 20.

The CPU 106 first places a bet preferentially on the bonus slot game(s) on the activated slot game areas A2 to A11 (step S51) after the bet switch 25 has been pressed or a medal(s) has been inserted into the medal insertion slot 21. After that, a bet is placed sequentially on the slot game on the activated slot game areas A1 to A11 in ascending order of the area numbers (step S52). Note that, the normal bonus game is not executed on the slot game area A1.

For example, when all of the slot game areas A1 to A11 are activated and the bonus game is being played on the slot game area A8, the first to third credits are bet on the bonus slot game on the slot game area A8 as shown in FIG. 20. Then the fourth credit is bet on the slot game on the slot game area A1 and the fifth credit is bet on the slot game on the slot game area A2. One bet is placed one by one on the remaining slot game areas A2-A7 and A9-A11 (except the slot game area A8 and the central slot game area A1) according to the above procedure. Then, the above procedure is repeated to place second and third bets. In this manner, thirty-one credits can be expended to place a 1-credit bet on the central slot game area A1 and a 3-credits bet on each of the other slot game areas A2 to A11, respectively.

An example has been described above, in which the number of activated slot game areas during the bonus game is one (slot game area A8). However, a 3-credits bet is placed preferentially on the bonus slot games on each of the activated slot game areas when the bonus games are executed simultaneously on two or more activated slot game areas. And then, one bet is placed sequentially on the normal slot game on each of the activated slot game areas.

FIG. 11 is a flowchart of another example of the bet processing. In this processing, the CPU 106 first places a bet preferentially on the bonus slot game(s) on the activated slot game areas A2 to A11 (step S61) after the bet switch 25 has been pressed or a medal(s) has been inserted, as in the case shown in FIG. 10. After that, a bet is placed sequentially on the slot game on the activated slot game areas A1 to A11 in random order (step S62). At this time, the bet order for the slot games on the slot game areas A1 to A11, which are not during the bonus game, is determined randomly by the CPU 106 at each game play.

As obvious from the above description of the present embodiment, the medal insertion slot 21 and the bet switch 25 correspond to the “input device” in claims.

Next, a jackpot bonus game processing procedure executed on the activated central slot game area A1 is described with reference to FIG. 12.

First, the CPU 106 determines stop symbols in each of the display areas q1 to q3 on the slot game area A1 (step S71). By this processing, symbols (“7”, “BELL”, “APPLE”, etc.) to be displayed in each of the display areas q1 to q3 are determined.

Next, the CPU 106 scrolls the symbols in each of the display areas q1 to q3 (step S72). Then, the symbols stop in each of the display areas q1 to q3 after a predetermined time has elapsed. Here, the displayed symbols are the stop symbols determined in step S71.

Then, the CPU 106 determines whether or not a jackpot winning combination (FIG. 17) has been rearranged (step S73). A jackpot payout is awarded according to a jackpot winning combination (step S74) when the jackpot winning combination has been rearranged. On the other hand, the CPU 106 does not award a jackpot payout and ends the jackpot bonus game when a jackpot winning combination has not been rearranged. It may be possible to cash-out a medal(s) equivalent to a jackpot payout amount through the cash-out chute 28 or to add a credit(s) equivalent to a jackpot payout amount to the internally stored credits, when a jackpot payout is to be awarded.

In this manner, the slot game areas A1 to A11 to be activated can be selected arbitrarily by the touch operation onto the slot game areas A1 to A11 on the lower display 16 in the slot machine 10 of the present embodiment. And then, the slot game is executed after a bet(s) has been placed on the activated slot game areas A2 to A11 (the normal slot game is not executed on the slot game area A1).

The jackpot bonus game is executed by the reels 3A to 3C on the central slot game area A1 when a jackpot trigger combination is achieved on at least one of the activated slot game areas A2 to A11, on which a bet has been placed.

As a result, in the slot machine 10 of the present embodiment, the slot games on the slot game areas A2 to A11 on the LCD panel 17 and the slot game (jackpot bonus game) on the slot game area A1 by the reels 3A to 3C can be executed continuously in a single game play if a jackpot trigger combination is achieved on at least one of the activated slot game areas A2 to A11, on which a bet has been placed.

Since a player can arbitrarily select the slot game areas A1 to A11 to be activated by the touch operation, the player can freely select the slot game areas A2 to A11 to play the slot game(s), on which a bet is to be placed. In addition, the player can freely select whether or not to activate the jackpot bonus game on the slot game area A1.

In the present embodiment, an example has been described above, in which the slot game area(s) A1 to A11 on which a bet (s) is to be placed is preliminarily selected. Then, a total bet amount is input and distributed on the selected (activated) slot game area(s) A1 to A11. However, it may also be possible that a total bet amount is preliminarily input and then the slot game area(s) A1 to A11 on which a bet(s) is to be placed is selected. Then, the bet amount is distributed on the selected slot game area(s) A1 to A11.

A slot machine of a second embodiment, which follows this procedure, will be described below with reference to FIG. 21 to FIG. 23.

As shown in FIG. 21, a slot machine 10A of the present embodiment differs from the slot machine 10 (FIG. 2) of the first embodiment described above in that a fix switch 30 and a selectable area counter 49 at the bottom right of the lower display 16 (the LCD panel 17) are added.

The fix switch 30 is one of the various operational switches disposed nearby the vicinity of the medal insertion slot 21 and the bill validator 22. The fix switch 30 is a switch for fixing a slot game area(s) to be activated among the slot game areas A1 to A11. A player is no longer able to select a slot game area(s) for activation the touch operation after pressing the fix switch 30.

The selectable area counter 49 displays the maximum number of slot game areas A1 to A11 that are selectable to be activated. If a bet amount, which has been input by pressing of the bet switch 25 or inserting a medal(s) into the medal insertion slot 21, is ten or less, the input bet amount is displayed as is in the selectable area counter 49. If the input bet amount is equal to or greater than eleven, a value “11” is displayed in the selectable area counter 49.

In the slot machine 10A of the present embodiment, the activation indicating frame(s) 51 of the selected slot game area(s) A1 to A11 is blinked between having been selected (activated) by touch operation and being fixed by the fix switch 30. Since the activation indicating frame(s) 51 is blinked, the player can easily recognize the slot game area(s) A1 to A11 on which a bet(s) is about to be placed.

As shown in a block diagram of FIG. 22, the slot machine 10A of the present embodiment differs from the slot machine 10 (FIG. 5) of the first embodiment described above in that the fix switch 30 is connected to the interface circuits 102 and the selectable area counter 49 is connected to the display control circuit 128.

In addition to the differences in outside appearance and electrical configuration described above, the slot machine 10A of the present embodiment differs from the slot machine 10 of the first embodiment in part of the processing executed by the CPU 106. The slot game execution processing of the present embodiment will be described below (in particular, the part different from that of the first embodiment).

FIG. 23 is a flowchart showing slot game execution processing that the CPU 106 of the slot machine of the present embodiment executes according to the game execution programs stored in the ROM 108.

First, the CPU 106 executes bet amount receiving processing for receiving a total bet amount on the slot games on the slot game areas A1 to A11 to be activated (step S101). In the bet amount receiving processing, pressing of the bet switch 25 by the player is detected and the total bet amount is calculated. Then, the CPU 106 subtracts the bet amount having been input from an internally stored credit amount (step S102). For example, if the stored credit amount is 50 credits and a 20-credits bet amount is received, the stored credit amount will be 30 credits.

It is also possible to input a total bet amount by inserting a medal(s) into the medal insertion slot 21. In this case, the CPU 106 recognizes the number of as a bet amount. In this case, it is not needed to execute subtraction from the stored credit amount in step S102.

Next, the CPU 106 calculates the maximum number of slot game areas A1 to A11 that can be selectable to activate based on the total bet amount and displays it on the selectable area counter 49 (step S103). Then, the CPU 106 executes area activation receiving processing for receiving a selection for activating the slot game areas A1 to A11 (step S104). In the activation receiving processing, the slot game areas A1 to A11, which have been touched by the player, are detected by the touch screen 72. The CPU 106 blinks the activation indicating frame 51 on the peripheral edge of the selected slot game area(s) to notify the player of the selected slot game area(s).

Next, the CPU 106 calculates the maximum number of selectable slot game areas and displays the calculated number on the selectable area counter 49 (step S105). The value on the selectable area counter 49 is reduced by one when one of non-selected slot game areas A1 to A11 has been newly selected. For example, the calculated maximum number is eleven when the bonus game is not being executed and none of the slot game areas A1 to A11 is selected yet. Here, the value on the selectable area counter 49 is reduced to ten when the slot game area A1 is selected for the right of the jackpot winning. In the downstream bet processing (the content of the processing is the same as that of the first embodiment), there may be the case where the bet amount is distributed preferentially (during the execution of the bonus game). For example, three credits can be expended at once when the slot game area, on which the bonus game is being executed, is selected. The calculated maximum number is eleven when the bonus game is being executed on one slot game area and none of the slot game areas A1 to A11 is selected yet. Here, the remaining number of bet amounts becomes eight when the slot game area, on which the bonus game is being executed, is selected at first. That is, the calculated maximum number is eight. In this manner, the CPU 106 calculates the maximum number of selectable slot game areas based on the total bet amount and distribution processing in the downstream bet processing.

Subsequently, the CPU 106 determines whether or not the fix switch 30 has been pressed (step S106). The CPU 106 determines whether or not the value on the selectable area counter 49 is “0” (step S107) when the fix switch 30 has not been pressed (step S106: NO). The processing returns to step S104 when the value on the selectable area counter 49 is not “0” (step S107: NO). On the other hand, the processing returns to step S106 when the value on the selectable area counter 49 is “0” (step S107: YES). The CPU 106 activates the selected slot game areas A1 to A11 (step S108) when it is determined that the fix switch 30 has been pressed (step S106: YES). The CPU 106 lights up the activation indicating frame 51 on the peripheral edge of the activated slot game area(s) to notify the player of the activated slot game area(s).

Next, the CPU 106 executes the bet processing for placing a bet on each of the slot games on the activated slot game areas A1 to A11 (step S109).

The CPU 106 determines a payline(s) to be activated according to a bet amount on each of the slot game areas A2 to A11 (step S110) after the betting processing has finished. Subsequently, the CPU 106 determines whether or not the start switch 27 has been pressed (step S111). The slot game is executed on each of the slot game areas A2 to A11 (step S112) when the start switch 27 has been pressed (step S111: YES).

Next, the CPU 106 determines whether or not the outcome of the slot games on the slot game areas A2 to A11 has met a prescribed condition (step S113). Here, it is determined that the prescribed condition has been met if a jackpot trigger combination has been achieved on the payline in any of the slot games (including the bonus game) on the activated slot game areas A2 to A11. The present processing ends when the prescribed condition has not been met (step S113: NO). On the other hand, the CPU 106 executes the jackpot bonus game on the central slot game area A1 (step S114) when the prescribed condition has been met (step S113: YES). After that, the present processing ends.

Each processing in step S109 to step S114 is the same as that in step S15 to step S19-1 (FIG. 6) of the first embodiment.

As described above, in the slot machine 10A of the present embodiment, the total bet amount is held after the bet switch 25 has been pressed or a medal(s) has been inserted into the medal insertion slot 21. Then, the maximum number of slot game areas A1 to A11 that can be selectable to activate is calculated according to the held total bet amount and then displayed on the selectable area counter 49.

Then, the slot game areas A1 to A11 are arbitrarily selected by the touch operation onto the slot game areas A1 to A11 on the lower display 16 within the range of the calculated maximum number. The total bet amount is distributed on the slot games on the selected slot game areas A1 to A11 (the slot game areas A1 to A11 on which a bet has been placed are activated). Then, the slot game is executed on each of the activated slot game areas A2 to A11 (the normal slot game is not executed on the slot game area A1).

The jackpot bonus game is executed by the reels 3A to 3C on the central slot game area A1 when a jackpot trigger combination has been achieved on at least one of the activated slot game areas A2 to A11 on which a bet was placed.

As a result, also in the slot machine 10A of the present embodiment, the slot game on each of the game areas A2 to A11 on the LCD panel 17 and the slot game (jackpot bonus game) on the slot game area A1 by the reels 3A to 3C can be executed continuously in a single game play.

In addition, since a player can arbitrarily select the slot game areas A1 to A11 to be activated by the touch operation, the player can freely select the slot game areas A2 to A11 to play the slot game(s) on which a bet is to be placed. Further, the player can freely select whether or not to activate the jackpot bonus game on the slot game area A1.

Further, in the present embodiment, the slot game areas A1 to A11 to be activated are selected after the total bet amount is determined. Therefore, since the maximum number of slot game areas A1 to A11 which can be activated is calculated preliminarily, it is possible to prevent a selection of the slot game areas A1 to A11 beyond the calculated maximum number.

Since a bet(s) is placed preferentially on the bonus game(s) on the slot game area(s) A2 to A11, the slot game area(s) A2 to A11 which is to be expected a larger payout by the bonus game can be activated without fail.

In the first and second embodiments described above, the slot game area A1 corresponding to a “specific slot game area” in claims is constituted by the mechanical reels 3A to 3C. However, the specific slot game area (slot game area A1) may be constituted by the LCD panel 17 in the same manner as that for the other slot game areas A2 to A11.

A slot machine of a third embodiment including such a configuration will be described below with reference to FIG. 24 to FIG. 27.

As shown in FIG. 24, the slot machine 10B of the present embodiment differs from the slot machine 10 (FIG. 2) of the first embodiment described above in that the slot game area A1 is configured by the LCD panel 17 instead of the mechanical reels 3A to 3C.

Because of the above difference, the reflective film 76 of the LCD panel 17 has the reflective area 76A extending all over the surface as shown in FIG. 25 and FIG. 26. The reflective film 76 does not have an area corresponding to the non-reflective area 76B of the first embodiment. In addition, the slot machine 10B of the present embodiment does not have elements corresponding to the fluorescent tubes 78 a, 78 b for illuminating the reels 3A to 3C and the lamp holders 79 e to 79 h of the first embodiment.

Further, the slot machine 10B of the present embodiment does not have components corresponding to the stepping motors 45A to 45C for spinning the reels 3A to 3C and the motor drive circuit 120 of the first embodiment. Then, the jackpot bonus game on the central slot game area A1 of the LCD panel 17 is executed under the control of the display controller 140 as the slot game on each of the other slot game areas A2 to A11. Therefore, the center area of the liquid crystal unit 74 is controlled so that it is not in a permanent inactive state but in an active state according to displayed contents.

Except for the above points, the slot machine 10B of the present embodiment is configured in the same manner as that of the slot machine 10 of the first embodiment.

As described above, it is possible to bring the same effect as that in the slot machine 10 of the first embodiment also in the slot machine 10B of the present embodiment by substantially the same operation as that in the slot machine 10 of the first embodiment.

The difference between the slot machine 10B of the present embodiment and the slot machine 10 of the first embodiment can be applied also to the slot machine 10A of the second embodiment. In other words, it is also possible to change the slot game area A1 (the specific slot game area) of the slot machine 10A of the second embodiment from the mechanical reels 3A to 3C to the LCD panel 17.

In the first to third embodiments described above, the slot game area A1 corresponding to the “specific slot game area” in claims is arranged in the center of the lower display 16, surrounded by the other slot game areas A2 to A11. However, the slot game area A1 (the specific slot game area) may be disposed not on the lower display 16 but at another different position, independently from the other slot game areas A2 to A11.

For example, as a slot machine 10C of a fourth embodiment shown in FIG. 28, the slot game area A1 (the specific slot game area) may be disposed on the upper display 33. The slot game areas A2 to A11 are disposed on the lower display 16. It is possible to dispose the slot game area A1 constituted by the mechanical reels 3A to 3C on the lower display 16 and the slot game areas A2 to A11 constituted by the LCD panel 17 on the upper display 33.

In this case, the slot game execution processing on the slot game areas A1 to A11 is basically the same as the processing in the slot machines 10, 10A, and 10B in the first to third embodiments. However, it is necessary to dispose an LCD panel behind the upper display 33 similar to the LCD panel 17 and control it by the controller 40 when the game area A1 on the LCD panel is disposed on the upper display 33 as shown in FIG. 28.

The slot machines and the playing methods thereof are described as above based on the embodiments schematically shown, however, the present invention is not limited to the above. The configuration of each part can be replaced with an arbitrary configuration having the same function.

For example, in the above embodiments, the examples are shown, in which the slot games are executed in all of the slot game areas A1 to A11 regardless of activation. However, it may also be possible to execute the slot games only in the activated slot game areas A1 to A11. Alternatively, a movie, which is looked like a slot game, may be played on each non-activated slot game area.
